METALLIC RAILWAY-TIE.

' Specification of Letters Patent.

Patented May 11, 1909.

Application filed July 2, 1908. Serial No. 441,695".-

Be it known that I, JOHN G. SNYDER, a citizen of the United States, residin at. Altoona, in the county of Blair and tate of Pennsylvania, have invented certain new and useful Im rovements in Metallic Railway-Ties, of W 'ch the following is a specification.

The invention consists in the novel construction, combination and arrangement of 'parts, hereinafter fully described, pointed outin the appended claim and illustrated in the accompanying drawin s.

In the drawings, in whic similar reference characters designate corresponding parts, Figure 1 is a sectional view of a device embodying the invention, the clamp being shown-in one ad'ustment.' Fig. 2 is a similar view showing t e clamp in another adjust ment. Fig.- 3 is a detail perspective view showing the clam Fig. 4 is a similar view of the clamping-p ate. Fig. 5 is a cross-sectional view of the tie.

The body of the tie is formed of a casing or shell of sheet metal and in general shape and dimensions is like the ordinary wood'en tie. It comprises the upper flat surface or crown 1 and the sides 2, the latter being spaced apart at their lower edges to form a wide opening extending longitudinally through the bottom of the tie. On the inside of the lower edges of the sides are the ribs 4 extending longitudinally of the tie. The casing or shell is adapted-to receive an elastic fillin of such a nature as to ive the required stability to the tie and whic will also permit it to ield to take up theshock of the passing loa The filling is held within the tie by the ribs 4. The wide 0 ening in the bottom of the tie allows the fil ing to contact with the material of the road-bed over a considerable area so displacement The ribs not only serve to aid in holding the filling within the tie, but prevent-injury to the edges of the flanges from the tamping-toolsemployed to lay the ti The rail is held in place on .the tie by the wedge-shaped clamp 5, formed at its inner or butt-end to fit over the base and against the web of the raiL In the'outer end of the v is the longitudinal recess 6 through whic the tie. Extending over the outerv end ofthe clamp is the holding or clampinglate 8 through which the'bolt 7 also exten s. At the buter end of the holding-plate is the downwardl turned flange 9 engaging the slot 10 in t e crown of'the tie.

, In securing the rail to the tie, after the former has been ositioned on thelatter, the clamp 5 is move until its.butt-end projects over the base and against the web of the rail. This adjustment of the clamp is allowed by the longitudinal recess 6 through'which the bolt 7 passes. By tightening the nut on the upper end of the bolt the several arts are forced together and held in place. hen the under face 'of the holding-plate is forced- ,are assembled and secured the several parts are firmly held in place The holding-plate through the bolt holds the clam down upon the tie and base of th'e rail,-an' the flange 9 registering with the slot 10 prevents any out-' ward movement of the plate and clamp. Having thus describe my invention, what I claim and desire'to secure byLetters-Patcut is, I I

A metallic railway-tie comprising a casing or shell provided with a slot' in its crown, a rail resting on the crown of said tie, a wedgeshaped clamp formedl'at its inner end to fit over the base and against the web of the rail and having a longitudinal recess inits outer end, .a holding-plate extendin at its inner end over the outer end of said 0 am a flange on the outer end of said holding ate registering with and vertically mova le in. said slot in the crown of the tie, and a bolt passing throu h the crown of the tie, the recess in said 0 ampand the holding-plate. In testimony whereof I hereunto affix my signature in the presence of two witnesses.
